Be it known that I, JOHN R. REYNOLDS, a citizen of the United States, residing. at

Hartford, county ofHartford, and State of Connecticut, have invented certain new and useful Improvements in Material, for VVaterproof Welts, fully described and represented in the following specification and the accompanying drawings, forming apart of the same. 1

This invention relates to a novel manufacture for forming watersproof welts which are used in water-proof boots and shoes.

It has been found desirable to employ in the manufacture ,of water-proof boots and shoes a welt of water-proof material,' this weltbeing used in addition, to the ordinary leather welt, being located bet-ween this welt and the upper and being secured inposition by the threads which forinthe seam which secures the welt to the upper. The form of welt which has been found satisfactory consistsofa strip of elastic material such as rubber, this strip having a bead on that edge which is to become the exposed edge when the welt is in position in'the shoe. As boots and shoes are now almost entirely made by machinery, it as practlcallynecessary that these strips be made in lo'ng lengths, say

from fifteen to thirty yards, and that they be uniform in their dimensions, so thatthey can be readily fed totheshoe making machinery in connection with-an simultaneously with the leather welt ordinarily employed. Difficulty has, however, been ex-' perienced in making the Well; in the long lengths referred to. Attempts have been made to form these welts by vulcanizing strips in molds. These attempts have not,

however, been heretofore successful for reasons which it is not necessary-to here state. Attemptshave also been made to iIOIlIl'lllllS welt by forcing plastic material through a dieso shaped as to produce a flat strip havmg a,rib or bead on one edge, These attempts were also unsuccessful for the reason that because of the unequal dimensions of the die on its opposite edges, the plastic material would flow faster through one side of the die than theother, thus producing a.

strip which was longer on one edge than theother, which strip could not be properly-handled in the shoe sewing machines.

The present invention has for its object to largely enters.

The novel material from. which the welts are to be formed consists of a strip of water- :proofsubstance, such, for instance, 'asrubber, 01" a compound into which rubber This strip'consists of a fiat central portion provided on its edges with beads or rounds, the strip. being intended and being adapted to be cut substantially midway between its edges to form two welts. Thefirst central portion is wide enough to .provide each welt formed by the cutting with a surface or part through which the securing stitches may ass to, secure the welt in 5 positionin the shoe, either between the upper and the sole or, more usually, between the upper and the ordinary leather welt, and yet permit the rounded or beaded edge to be exposed. In the particularconstrucvtion illustrated, the strip is show ngas having a flat central portion 1 and beaded ed es 2, It has been found by experience t at a strip having rounds or beads can be readily produced by forcing plastic waterproof materialthrough a suitable die, aosuit-abltn 'process for making this strip bein disclosed in Patent N 0; 811,793, grante Feb ruary 6, 1906, and the'strip thus produced will have uni-form edges and be uniform in thickness along its central portion. This strip'can be readilyconverted into welts by cutting it substantiallymidway between the edges.
